Specification of Letters Patent.

Patented J lily 13, 1915.

Application filed June 18, 1914. Serial No. 845,866.

To aZZ whom it may concern Be it known that I, EDWIN E. HANSON, a citizen of the United States, residing at Se attle, in the county of King and State of \Vashington, have invented certain new and useful Improvements in Igniting Implements; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to igniting devices, and more especially to those intended particularly for use with a gas or hydro-carbon burner or stove; and the object of the same is to produce a simple and eflicient implement of this kind working on the principle of a flint lock, and wherein the wearing parts are readily replaceable.

Details will appear in the following specification and claims and are shown in the drawings wherein Figure 1 is a bottom plan view of this implement; Fig. 2 is a side or edge view thereof; Fig. 3 is an enlarged section on the line 33 of Fig. 1; Fig. 4 is a side elevation partly in section showing a slightly different form of this invention applied to a gas plate of an ordinary gas range; Fig. 5 represents a top plan view thereof; Fig. 6 is a horizontal section thereof taken on the line 6-6 of Fig. &, looking in the direction of the arrow;

Fig. 7 is a detail side elevation showing the igniter in the act of producing a spark; Fig. 8 is a transverse vertical section taken on the line 88 of Fig. 4L; and Fig. 9 is a transverse section taken through a gas pipe showing slightly different means for attaching the igniter to said pipe.

In the form shown in Figs. 1 to 3 of the drawings the numerals 1 and 2 designate arms having handles 3 at their rear ends, and pivotally connected with each other at the point 4: much after the fashion of a pair of scissors but so that one arm 2 overlies the other arm 1, and they are shown in Fig. 1 as reversed from this position. Theupper arm 2 carries at its outer end a pendent curved flange 5 struck on an are around the center 4, and at one end this flange is bent inward into a lip 6 which constitutes a stop in the manner yet to be described. Secured removably to the inner side of this flange as by screws 7 is a ratchet-toothed file or scratcher 8, the upright sides of its teeth preferably disposed toward the lip 6 and the beveled or inclined l is secured as by rivets 10 a sheet-metal casing 11 (the bottom face thereof being omitted in Fig. 1 so that the parts within it can be seen), and within this casing is slidably mounted a flint 12 or its equivalent. The flint (so called throughout this specification) is projected forward by means of an expansive spring 13 within the casing 11 bears against the rear end of the flint, and 14% is a set screw through the rear end of the casing against the spring whereby the tension of the latter may be adjusted as desired.

The parts are of any desired materials and proportions. and their construction need follow only roughly the description given above as I reserve the right to make changes in details such as will not depart from the principle of the invention. In action the operator takes the device in his right hand, with his thumb passing through the smaller loop and his first two fingers through the larger, and moves the loops apart so that the projecting end of the flint 12 travels over the file-teeth until the forward end of the arm 1 strikes the lip 6 which acts as a stop to prevent the arm being pushed too far in that direction. Then placing the tool in position about five inches, above the burner or other article which it is desired to ignite, the operator draws his thumb and fingers suddenly toward each other which causes the arms 1 and 2 to rock on their pivot a so that the tip of the flint is moved rapidly over the file-teeth 8 in such direction that these teeth produce a spark, and the spark lights the gas in a manner which will be clear. At such time the casing for the flint is on the lower side of the implement, although this exact disposition is not absolutely necessary to the successful use of the device. When the handles come together the tip of the flint should not be be yond the end of the file. These handles therefore limit the movement of the arms in one direction, whereas the lip 6 serves the same function when the arms are moved in the opposite direction. In order to replace the flint, said lip may be bent aside, as it is by preference made of pliable material, or if the uppermost arm 2 is sufficiently flexible it can be bent until the lowermost arm 1 can be passed over the lip, when the flint is exposed and can be readily replaced by a new one.

In the embodiment shown in Figs. 4:, 5 and 6 a slightly different form of igniter constructed on the same principle as that shown in Figs. 1 to 3, is applied to a gas plate of an ordinary gas range, said plate being here shown at P which extends upwardly from the ordinary gas pipe 2) which is connected with a main supply pipe 3) arranged in a plane at right angles to the pipe 79.

Clamped on the pipe p adjacent the burner plate P, is this improved igniter, the means for securing it being here shown in the form of semitubular clamping members 15 and 16 which are shown hingedly connected at 16 and the meeting jaws or flanges at the opposite side thereof are here shown provided with a set screw 17 for securing said semitubular jaws to the pipe 7). An arm 18 extends laterally from this clamp and has a shoulder 19 projecting therefrom and having an outwardly extending depending obliquely disposed arm 20 thereon.

A. flint containing tube 11 is secured on the clamp and extends upwardly therefrom and in which is disposed a flint or ignition element 12 which is projected into operative position by means of an expansible spring 13. An L-shaped member 21 is here shown pivotally mounted on the clamp adjacent the shoulder 19, the longer arm of said. member having an apertured ear 22 by means of which it is pivotally connected to the clamp at a point adjacent its free end. Said free end is here shown apertured for a purpose to appear. The short arm 23 of this member 21 is here shown arcuate to provide an element for cooperation with the flint or igniting member 12, the inner edge of said arm 23 being here shown serrated or roughened as at 24: to form an operating element for engagement with the flint for producing a spark when said head or short arm 23 is moved over the flint. A pin 25 is removably inserted in the free end of the arm 23 and extends edgewise therethrough into the path of the tube or casing 11 for limiting the movement of the head 23 in one direction, and preventing it from being accidentally moved past said tube. The pin is made removable to facilitate its withdrawal for allowing the head to be pulled back when desired to expose the tube 11 for changing the ignition element.

A plate spring 26 is shown secured at Copies of this patent may be obtained for one end to the inner face of the long arm 21 of the movable member and bears at its other end on the tube 11 exerting its ten sion to normally force the movable member away from the tube 11 so as to position the free outer end of the arm 23 over the flint and in substantially vertical position.

A coil spring 27 is secured at one end to the free end of the arm 20 and at its other end to the free end of the arm 21 of the movable member and exerts its tension to hold the igniter away from the burner plate P when not in action and to permit the movable member to move forward by means now to be described. A flexible element 28 which may be constructed of a wire chain or other suitable device, is connected at one end to the free end of the arm 21 of the movable member and at its other end is connected to a lever 29 fulcrumed at one end on a collar 30 shown mounted on the main pipe 7) and which when moved outward causes a pull on the element 28 and draws the free end of the long arm 21 of the movable member against the tension of the spring 27 and thereby moves the short arm thereof inward toward the burner over the ignition element 12 thereby producing a spark for igniting the gas.

In Fig. 9, is shown a slightly different form of the device in which a three joint arm 31 is employed for connecting the i niter to the pipe to provide for its adjustment to fit burners of different heights and positions, said arm being held in adjusted position by set screws.

1 claim as my invention:

An igniting implement comprising a pair of flat arms pivoted scissors-like relative to each other with their flat faces movable .one over the other, one arm being shorter than the other and the longer arm having a laterally extending arcuate operating member secured at the end of the face over which the shorter arm moves and beyond the outer end of said shorter arm, a casing disposed longitudinally on the outer face of said shorter arm and open at its outer end and closed at its inner end, a longitudinally movable igniting element mounted in said casing with its outer end extending into the path of said operating member, a spring for projecting said element, and means for varying the tension of said spring.

in testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
